Standard Letterplate
The default Endurance plate — softly radiused polished chrome with a sprung, brush-sealed flap. The safe match for lever/lever and lever/pad handle sets on modern and traditional doors alike.
Draught-tight, fully insulated, tested to Royal Mail spec.
A composite door only performs as well as its weakest hole, and the letterplate is usually it. Every plate we fit uses twin nylon brushes, a spring-loaded inner flap and a fully gasketted frame so the door still hits its 1.4 U-value.

Genuine Endurance hardware, photographed as supplied. Every option below can be specified on any door we install in Cornwall.

The default Endurance plate — softly radiused polished chrome with a sprung, brush-sealed flap. The safe match for lever/lever and lever/pad handle sets on modern and traditional doors alike.

Flat, square-edged plate with a slim recessed aperture. Designed to pair with the Architectural lever and knocker range on contemporary slab doors.

The same square-edged architectural profile in a deep matt forged black. The most-specified plate on anthracite, black and French Navy doors across Cornwall.

Hand-finished pewter with a lightly textured, mottled face. Sits beautifully against Chartwell Green, Sage and Claystone doors on period and cottage properties.

Deeper stepped surround with a heavier weighted flap — the traditional choice, and the one we spec on exposed coastal doors where wind loading is highest.
Every option below is stocked, tested and finished in-house before it goes on your door.
The everyday size that Royal Mail expects — takes A4 magazines without folding.
Fitted with an internal metal shroud that prevents lit material or liquid being posted through — insurer-approved on rented properties.
Wider aperture for broadsheets and mail-order packets, still fully draught-sealed.
Recessed behind the door for a clean façade — post drops into an internal catcher tray.
Every finish is available across the range and matched to your window and letterplate hardware for a consistent look.
